December 7, 2004 An implantable, brain-computer interface the size of an aspirin has been clinically tested on humans by American company Cyberkinetics. The 'BrainGate' device can provide paralysed or motor-impaired patients a mode of communication through the translation of thought into direct computer control. The technology driving this Brain-Machine-Interface breakthrough has a myriad of potential applications, including the development of human augmentation for military and commercial purposes.
